Patent CA-2033844-A1 (CA)
Inventor: ROTH ROLAND
IPC: B29C55/02
Filed: 1991-01-09
Abstract: METHOD OF AND APPARATUS FOR MAKING LAMINATES FROM           POLYETHYLENE FOILS AND THE LIKE   ABSTRACT OF THE DISCLOSURE An unstretched first plastic foil is laminated with a longitudinally stretched second plastic foil by the application of heat and pressure.  The second foil is preheated, thereupon stretched and thereafter tempered prior to being laminated with the first foil which is heated prior to lamination.  The laminating step can coincide with the tempering step and immediately follows the stretching step so that the laminating step can be carried out by utilizing heat which is required for stretching of the second foil.  The material of the first foil is or can be identical with the material of the second foil; in any event, the two materials are sufficiently compatible to permit bonding of the unstretched foil to the stretched foil by the application of heat and pressure alone, i.e., without resorting to an adhesive.

Title: Method and apparatus for digital switching of fm signals with reduced crosstalk
Inventor: COOPERMAN MICHAEL
IPC: H04Q3/52
Filed: 1991-11-13
Abstract: METHOD AND APPARATUS FOR DIGITAL SWITCHING    OF FM SIGNALS WITH REDUCED CROSSTALK            ABSTRACT:     Apparatus  for digital  switching of FM signals includes multiple functional  switching circuits,  each having an input for receiving an FM signal at a first frequency and each generating first switching transients in response to the FM signal.  The apparatus includes a dummy switching circuit corresponding to each functional switching circuit. The dummy switching circuits generate second switching transients in response to the FM signal. The second switching transients are shifted in phase relative to the first switching transients such that a crosstalk signal resulting from the first and second switching transients has a frequency of twice the first frequency.  The apparatus further includes filters for attenuating the  crosstalk  signal.   By  shifting the frequency of the crosstalk signal to twice the frequency of the FM signal, the crosstalk signal is easily filtered.

Title: Foil-like material for a folding package and such a folding package
Inventor: MORENO DAMASO
IPC: B65D75/58
Filed: 1990-05-19
Abstract: ABSTRACT            Foil-like material for a folding pack and such a folding pack A folding pack (10) is produced from a single foil sheet (12) which is so folded round an article to be packaged and is so closed that the article is surrounded by it on all sides in an airtight manner.  The closure is obtained by means of an adhesive bonding of the in each case mutually opposite edge regions of the foil sheet which laterally frame the inner region of the foil sheet. According to the invention, two mutually opposite edge regions (26, 28) each have at least one not permanently adhesive region (50, 60, 72, 74), these regions being located one above the other (24)  in the state folded together to form a folding pack (10), and one of these two edge regions (50, 72) is partially separated materi-ally along its peripheral line (54,  70,  52)  from the remaining edge region  (26).   At the  same time,  the adhesive layers (40, 42) are respectively present between these two regions  (50,  60 and 72,  74)  and the inner region (22, 14, 16, 18, 20), in such a way that the inner region is completely framed laterally by the adhesive layers (40, 42).

IPC: B02C11/04
Filed: 1992-03-25
Abstract: ABSTRACT OF THE DISCLOSURE:            A tub for grinding livestock feed on a rotary cutter. The tub has a rotating circular sidewall and two spaced apart, inwardly  facing,  deflecting  baffles  that  are  pivotably mounted to the sidewall and pivoted in unison by an arcuate arm spring-biased to the sidewall.  The arm may slide from a first position in which it can be held by a stop, to a second position upon release of the stop.  When the arm is in first position, the baffles are held along the inner wall so  as  to  free  the  center  of  the  tub  for  top-loading livestock feed.  Upon release of the stop, the arm is biased toward the second position where the baffles extend toward the center of the tub following the contour of the livestock diminishing in size as it is shredded by the rotary cutter. The baffles may have a spring-biased swingable lower portion that swings backward upon encountering obstacles in the tub.

Patent CA-2065327-A1 (CA)
Title: Chest protector
Inventor: LABERGE RAYMOND
IPC: A63B71/12
Filed: 1990-08-28
Abstract: Sports player protective equipment having a system of protective padding members, and of a scale-type configuration having one section of protective padding overlapping an adjacent section of protective padding. The padding sections overlap one another and include a sliding extension member, the end of which is secured to an approximate midsection of an adjacent padding section so as to allow sliding movement of one padding section relative to an adjacent padding section. This sliding movement allows for expansion, contraction and rotation of the entire arm protective padding, which provides improved freedom of movement with greatly increased capability of bending of an arm. Advantageously, the arm protective padding sections are capable of extension, contraction and rotation with respect to each other without diminishing protective capability. Therefore, a single chest protector fits different sizes of players due to the extension and contraction capabilities of the arms. Further, the arm protector sections are able to compensate for the twisting or rotation of the arms of the player during play. It is also possible for the hands of the player to rotate at least 180· without loss of protection to the arms.
